AN OPTIMIZATION STUDY ON DISSOLUTION OF THE CALCINED COLEMANITE MINERAL IN METHYL ALCOHOL BY CO2 IN AN AUTOCLAVE SYSTEM USING TAGUCHI METHOD

Abstract

The process of optimizing the dissolution of colemanite ore (2CaO.3B₂O₃.5H₂O) in methyl alcohol by CO₂ in a high-pressure reactor was evaluated by using the Taguchi method. Optimum conditions for the cholemanite mineral were determined to be as follows: reaction temperature: 140°C, reaction time: 50 min, calcination time: 240 min, calcination temperature: 450 ^oC, solid-liquid ratio: 1/6 g.mL^-1, mixing rate: 500 cycle/min, pressure: 20 bar, grain size: -100 mesh and the amount of CaCl₂: 7.5 g.
